To all 'who-m. 'it may concern.' i

Be it known that I, JAMES L. DALTON, a citizen of the United States,residing atv Pop- Alar Bluff, Butler county, Missouri, have in-v venteda certain new and useful Adding and ,Recording Machine, of is aspecification.

This invention relates to adding and recording machines, and moreparticularly to machines of ,cross-carriage type such for instance asthatshowxi in an application of Hubert Hopkins filed-January 24th 1903-,Serial No.4140,390, eventuating in No. 1039130, dated September 24,1912.

mechanism whereby two or more separate totals may be carried in themachine'at the same time. j 'i The .total mechanisms whereby theseparatey totals are computed and. carried co operate with recordingmechanism operable to record the items'including in the totals and alsooperabletorecord the totals and to clear the` total mechanisms, orpermit the latter to retain the totals therein as sub` totals to beincluded in a iinal grand total. Other objects'and manifold advantages'of the present invention will become apparent from the followingspecification, Areference being nade-to the iaccompanying draw` .ings inwhich: l

The machine as at presentwillie-market includes a key-board on which-thekeys-1 are arranged inconvenient manner in transverse rows, thel stemsofpthe v.keys-extending through slots in the Vkey-board .plate-and beingconnected with, or formingpart o f the key-levers Q, which projectrearwardly and converge at their rear ends and aregprovided withvertical extensions 3 arrangedhin the same vertical plane. Twotransverse rails l are supported near the rear end ofthe machine and thecarriage 5 isl providc-djvith rollers G operating above said rails.

gages under one of the rails and thereby prevents derailment of thecarriage 'during operation and during movement and 4transportation ofthe machine. .lVithin the carriage 5 the vertically movable pins 8 areupwardly and at the same time the carriage 5 will be moved one steptoward the left A hoolt 74 attached to one side ofthe carriage cn- F ig.15 shows the -lower position'p thestopwhich is sutiicient' to positionthe second row of pins in said carriage above the termini 3. Thisleftward movement of the car- Acal shaft 11, andzthe gear segment 12 onthe yupper end of -said shaft 11 enmeshed with a rack13 rigidlyconnected to one side of the 'far'ria e 5. The escapement 9 has a lbar14 exten ng over the key levers 2 whereby the eseapement will'beoperated at ea'eh operation cfa key. In this way by successiveoperations of the-keys any number may be set up or registeredin thecarriage 5, the pins 8 beingfpositioned to represent the digits ofanumber. After the number has thus been represented in the carriage,such number may be recorded and added.

The recording-mechanism comprises a series of type-carriers 15 vswingingfrom a shaft 16, said type-carriers being arcuate in Aform and extendingforwardly. On the forward end of each typ-carrier is a series oftype.17,vsaid type 'lining movable with respectfto the type-carriers. A'platen 18 is ,attached on a shaft 19 mounted in a carriage 20 and isoperable in connection with the feed rolls 21 to feed the paper acrossits front surface where records may be made by driving. the type 17against an interposed ink ribbon. Coperating with each type-carrierthere is a member 22, said membor swinging from the shaft 16 andprovided on their lower ends with arcuate racks 23. ASaid membersi22have .extensions connected by pin and -slot connections 24* with the tpe-carriers 15 so that each type-carrier to the length of its slot. Theracks 23 are spaced apart the same distance as the-space Aseparating therows of 'pins 8 in the carposition of the parts, the plate 25 is underthe racks 23 and the rear edge of the plate is' supported immediately infront of the heels 24 so that when type-carriers and racks are-actuatedforwardly, their forward movement will be stopped by the. heels 2lcoming into contact with the rear edge of the plate In the presentinstance, the arrangement is such that the four racks at the rightrelative to the operator will engage with as independent movementequivalent the lower portion of the plate while the five remaining rackswill eng-ige with the upper portion of the plate When the carriage 5 ismoved leftwardly as before described,the plate 25 is also transportedleftwardly and at each step moves from in front of one of the heels 2lso that as many racks and type-carriers will be free to move` forwardlyas there were figures in the nurnber set up in the carriage. `After thenuml ber has been thus'set up in the carriage and the type-carriers.have advanced to their forward positions and been properly positionedby engagement of the heels 2l with the pins 8, the number represented bythe type 17 atthe'printing line will be automatically recorded by a setof hammers 28 striking the front ends of the type. Return movement ofthe type-carriers and racks is effected by a rod 29 supported in frontof .the vertical portions of the ltype-carriers and racks by arms 30depending from the shaft 16, said rod being moved in anyconvenient'manner. Total wheels 3l are arranged to become enmeshed withracks 23 on return movement of said racks thereby to add the items afterthey are recorded.

After any series of items has been added,

the total represented in the wheels 31 may be recorded and said wheelsrestored to clear position or the total may be retained in' the wheels.The mechanism for accomplishing this result as embodied in the machinesof the character referred to at present on the market, and as disclosed,for instance, in I the British patent to Hopkins, No. S51, of 1904,includes a totals recordingr key 32 having a steml projecting through aslot in the key-board plate and pivoted at its lower end tothe front endof a lever 33, the rear end of which extends under the horizontal arm ofa bell-crank 34. A link connects the bell-crank 34 with a lever 3()pivotcd to a shaft 37 at. the rear oi the machine. Said lever 36 alsoprojects above the shaft 37 and an arm 38 pivoted on thc shaft 37coperates with the upper portion with the lever 3G to support ahorizontal rod which will be swung forwardly whenever the total key isdepressed. A cam plate ll-0 is mounted in the carriage 5 and is providedwith an oblique slot 4l in which a pin on an extension of the plateprojects. SV hen the total key is depressed and the rod 3) is swungforwardly, said rod will engage against the rear end of the cam-plateel() and push said plate fcrivardlv thereby drawing downwardly tbe plate25 untiLthe lower portion of said plate at tile right ot the cut 27 isentirely below the hecls of the four racks at the right. This willpermit said racks and the coiliera'ting type-carriers to move forwardly,the racks `remaining enmeshed with the total wheels whih the totalsrecording key is down and being 'stopped thereby. ln this-way the totalcon" tained in thefour Wheels at the right relaf- The'meclranism so f rdescribed iscontained -i n"the machine as et present on ,the

By-mechzinisnr of this churiicter vin-ions kinds of work maybe' performed on the machine. For instance, parallel columns of itemsmuy be recorded simultaneously as shown at the top of`Fig. 2 andseparate totals thereby may becarried in the machine at the same timeand then recorded simultaneously. Again, one column of items may berecorded by the type-carriers at the right relative to the operator asshown at A in Fig. 2 and the total of such column recorded as shown at`B. Then this total may be introduced in the machine through the keys 1and the carriage 5 and recorded as an item or sub-total in a column atthe left of the column A as shown at C. Then other items may be recordedin the column A a total thereof recorded in the same column and thistotal again introduced into the machine and recorded in the column C, asitem or sub-total, after which the total of the numbers recorded in 'theleft hand column may be recorded as shown at D. A third specimen ofthe\work of which this machine is capable of performing is shown at thebottom of Fig. 2 in which two columns oi items are vrecordedsimultaneously and the totals thereof recorded at E and F, respectivelyand the machine cleared. After the totals have been thus ascertainedthey may be again introduced into the machine and recorded in one columnor other as sbowr at Gr making a grand 'total H. The machine may also beused to perform work of various other kinds, but vthe Specimensillustra-ted are sufficient to enable those skilled in this art tocompre! hend the nature and. the purpose of the invention. It will beIunderstood, of course, that the machine performing this work, may besplit so that the ciphers at the 'right of the numbers in th'e left handcolumn or columns will not be recorded, thereby enabling the operator tolist a single column of numbers on the left or parallel columns printedsimultaneously, specimens of both of which are shown' in Fig. 2.

I am aware that' there may be lvariations' in the constructions,combination and arrangement of this invention Without the leastdeparture from the spirit and scope of the invention. Also that themachine may be used to perform various classes of work other thanthoseillustrated and l do not restrict myself to specific constructions orarrangement nor to specific functions, but what I claim and desire tosecure by Letters Pateneis: g
